CS8 to X8 conversion - Herkules ESC III V3

[Vortex]

Yes, both test with Graupner 14x8.
Next week i will test the 6S with Xoar 15x5 / 15x6.

That was the next thing I was going to ask.......Looking forward to seeing how it goes.

Lance

Mk-thor. In the 6S 13.5 kg video. what portion of this weigh was frame,and batteries and which one was payload?

Boris Send this Santa to me too please.

Japp the DC 16 is really amazing just love the menu. No restriction can't do this or that this switch only for that, like usual, just clever programming and best design I have seen up to now. But it would be cooler if they wouldn't have put on the duplex 2.4 writing that big. Kills the design a little.


Bird is getting bigger than thought but i guess it will visually smaller once the carbon tubes are cut for the holders. Enouggh space for 4x 10000 6s All on the Landinggear hope it has the vibration reduction effect i am hoping for !

Boris it would be nice if the legs from the gimbal would be removable for fast storage. Maybe something like this:

[BorisS]

japp ! I have the possibility now to take of the Landinggear since it attached with the s800 method of these 6 hand screws things.

But you are right for the zenmuse these are very good ! was eyeing them yesterday already

Thor are you boin to go Binger with the prop Size 16 ? And Andreas was Talking about that he is testung the dualsky 340 kvs. Did you have your Hands on them yet and impressions ?

Thnaks

Boris

 

[Vortex]

mk-Thor.....Thankyou for the figures....It helps put it into perspective now!!!

[BorisS]

Redesign my X8 conversion completely so its gonna take some more time ;(

If i only had a reliable good quality cnc service here in europe hint hint !

[elossam]

Boris ask mr Xavi from uaveurope for cnc requirements http://www.uaveurope.com/

 

[BorisS]

thanks gonna send him a mail !

@Boris, (how are you) hi.... this is my new babe ... with Herkules
But i dont now what Motor that i can use on my little skyliner ,-)

looks fine ;-)

 

[BorisS]

HI Mtec,

depends on the FC you are going to use payload you want to lift, cam gimbal you are going to use as in traditional with servos or a direct drive etc. For me personally the only combo at the moment that makes sense it low KV and 6s. MOre KV smaller props might give more stability with some FCs. But what do it want stability for, for
nice footage. But if you are using a gimbal like the zenmuse who cares, I prefer to give in to smoothness a little and go for longer flight times. Although most of the X8 DJI based all fly very smooth. Its more th lat octo that the WKM seems to struggle with still.

Three candidates I consider very interesting.

1. KW9
2. Navigator series
3. Dualsky http://www.himodel.com/electric/DUA...k_Type_Motor_for_Multi-rotor_Short_shaft.html, heard some good reports about them. But didn't have the balls yet to base a whole system on them.

Hi guys,

just stumbled across this thread.
Take a look at this motors:
www.rctigermotor.com

Lots of scalable variants even with low RPM (400kV) => ideal for 6S...;-)

Available e.g. at www.globe-flight.de or www.kopterworx.com

i test this combination...

 

[BorisS]

so slowly finishing up the build parts finally went out to the water jet cutter machine, Decided to use that instead of a cnc.

at the moment setup for the zemuse gh3 modded.

Lets see if the vibration mounts work otherwise I have other ones in the works. Once the 3d printer is here they should be easy to produce in house.

so slowly finishing up the build parts ....QUOTE]

Hi Boris,

Have you actually flown yet with those Secraft v3 Pro retracts? The design is plainly far superior to the v1/v2 but I am still not happy with them. The vibration that is introduced to the whole airframe as a result of the small amount of play in the hinges is really just an amplification of existing vibes, but it becomes a problem because it gets through to the Zenmuse. The Zenmuse can handle standard vibrations but not these amplified ones. I even had one leg collapse on the table (right onto my bloody cell phone screen and the Zenmuse!). It is important to limit servo travel to avoid this.


Another big minus point is their tendency to occasionally operate upon power up. Not good when still on the ground. Because of this I had to install a small extension so that the retract servos could be connected AFTER the rest of the radio and MR was powered up, but extra little procedures like this are not needed when you are busy with a job. It is the sort of thing that can get forgotten until suddenly the whole airframe collapses onto the camera mount during a power up and the day's filming is over !
